Here is part of my actual code, if that makes any difference.
$password // this var was retrieved from db
$int_id // this var was retrieved from db
$file_array = file("$DOCUMENT_ROOT/dir/file.dat");
$count = count($file_array);
if ($count == 0)
echo "<p>No records found in .dat file.</p>";
for ($i = 0; $i < $count; $i++)
{
if (eregi("^\$password+[[:space:]]*+\$int_id", $file_array[$i]))
{
// do stuff
}
}

but if the positions as fixed, why don't you use the substr, and then trim
th result?
